• Pre-lab
• 1. What ions are present in the following
  solutions?
• NaCl(aq) ? ____________________ AgNO3(aq)
  ? ____________________
• When these solutions are mixed together, a
  precipitate is seen. What are the new
  combinations of ions that could have formed the
  precipitate?
• ____________________ and ____________________
  
• Using the solubility table, which new combination
  will form a precipitate?
• ____________________ ?
• Which new combination will remain in solution?
• ____________________
• 5. Write the overall reaction equation for this
  reaction. Be sure to indicate the correct phase
  (reaction condition) for each reactant and each
  product.
